Can I eat non halal slaughtered way chicken while on an educational trip?

Asalamalaikum. I live in US but I'll be going on an educational trip to Argentina and Chile for 2 weeks and over there I'll be with my College peers and professors to even go to restaurants with them. I may not get halal food over there and also hardly any vegetarian. So, I'm wondering is it allowed for me on the tour to eat non-halal way slaughtered chicken? I've seen Muslims in US eating non-halal way slaughtered chicken by simply saying Bismillah (I know this is not allowed) But is it allowed on a trip? Thank you
